MEANS FOR FASTENING TIPS TO UMBRELLA R-IBS.

Application filed February 12,1924. Serial No. 692,225. y

To @ZZ whom t may concern Be it known that we, JOHN LUTZ and VAYNE S.EVANS, bothv'citizens of the United States, residing in the city andcounty of Philadelphia, State of Pennsyl- Vania, have invented a new andusef ful Means for Fastening Tips to Umbrella Ribs, of which thefollowing is a specification.

This invention generally stated, relates to,

umbrellas, parasols, sun-shades and the like and has more especialrelation tothe provision of novel means for securing a tip to the endsof paragon or fluted ribs thereof.

When reducing the end of a paragon or tinted rib for the purpose offorming a cylindrical portion for the outer end thereof to receive aCelluloid or bone t-ip, it is common practice to make said cylindricalportion slightly tapered fromthe rib body toward the rib outer end. ACelluloid or b one tip is then positioned over Said tapered portion ofthe rib and secured thereto by means of glue or the like. Such proceduretends not only to slow down production but results in amore or lessunsatisfactory product or article of manufacture, since tips secured inthis manner frequently separate from a rib `due to various causes. Theleading object of the present invention is to overcome the abovedescribed disadvantageous features and to provide a ribtip constructionwherein the tip is frictionally retained on the rib by novel means andnot only is production expedited but a more efficient and durablearticle is produced at less cost.

A further object is to provide a. co-inbination, connection andarrangement of parts for attaining the results sought by said leadingobject. Other and further objects notl at the time appearing will behereinafter referred to.

For the purpose of illustrating our invention, we have shown in theaccompanying drawings, forms thereof which are at present preferred byus, since the same will give in practice satisfactory and reliableresults, although it is to be understood that the variousinstrumentalities of which our invention consists may be variouslyarranged and organized and that our invention is not limited to theprecise arrangement and organization of these instruinentalities asherein shown and described. Figure l, represents a perspective view ofa. portion of 4an umbrella, parasol, sun-shade" or like rib illustratingthe construction of the tip-receiving end.y I

Figure 2, represents a View in cross-section, taken upon the line 2--2of Figure 1.

Figure 3, represents a View in plan of the parts shown in Figure l,

Figure 4, represents Ya view in longitudinal section of a rib havingapplied thereto a celluloid or other tip in accordance with the presentinvention.

Referring to the drawings:-

Inl the practice of the invention an end of a paragon or fluted rib isreduced by bending over of the opposed marginal portions to form atubular portion l, which Yextends from the body portion 2 outwardly, andis of uniform cross-section throughout its extent. The juxtaposed edges3 3 of the tubular portion'are spaced apart form4 vof the portion l, andat the junction of said parts l and 5 there is formed an annularshoulder 6. 7 designates a tip, made of any desired suitable material,and which may be of any desired configuration, as fashion dictates; suchtip is provided with a central, elongated uniform bore 8, which is of adiameter to properly receive the part l, of the rib 2. The smallersection 5 is slightly smaller than the diameter of the hole 8, in thetip 7, while the larger section 3 is slightly larger than the diameterof said hole-8. n l

To position a tip'7 upon a rib 2, the terminal 5 is inserted within thebore 8 of said tip, which serves to center the tip with respect to saidrib. By moving the rib and tip towards each other in any suitablemanner, the bore of the tip completely covers theresilient bearing l, ofthe rib. Since ythe edges 3 3 of portion l are spaced apart,

a tight it between the tip 7 and rib 2 can be effected since a yieldingbearing is pron if desired.

It will be understood that the terminal 5 is substantially a cylinder incross section, as is also the larger section l, whose walls are slightlyflared as at 9 where they merge into the body of the rib 2. The bore orhole 8 in the tip is also substantially a truc cylinder, so that whenthe parts are assembled as seen in Figure 4, they are in tightfrictional engagement. Y

It will now be apparent that we have devised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above descriptionand while we have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to givesatisfactory and reliable results, it is to be understood that the sameis susceptible of modification in various particulars ywithout departingfrom the spirit or scope of the invention or sacrificing any of itsadvantages.

`Having thus described our invention what we claim as new and desire tosecure by Letters Patent, is

1. In a device of thecharacter stated, an umbrella rib having the' endthereof formed into two differentsections, the terminal section beingthe smaller diameter and the juxtaposed edges of saidv sections beingseparated by a longitudinally extending slot, so as to permit said edgesto be compressed towards'eacli other.

2. In a device of the character stated, an umbrella rib having the endthereof formed into two different sections, the terminal secw tion beingthe smaller diameter, and the juxtaposed edges of said sections beingseparated by a longitudinally extending slot, so as to permit said edgesto be compressed towards each other, said larger section being flaredand merging into the walls of the rib.

3. The combination of an umbrella tip having a hole of substantiallyuniform diameter therein, and an umbrella rib having the end thereofformed into two different sections, the terminal section being thesmaller diameter, and there being a longitudinally extending slot insaid sections to permit compression of the latter, so as to hold saidtip inposition on said rib by frictional contact.

4. The combination of an umbrella tip having a hole of substantiallyuniform diameter therein, and an un'ibrella rib having the end thereofformed into two different sections, the terminal section being thesmaller diameter,l and there being a longitudinally extending slot insaid sections to permit compression of the latter, so as to hold saidtip in position on said rib by frici tional contact, said larger sectionbeing flared outwardly and merging into the walls of said rib.
